Google Play, the search company's app and content store, shares the name, email address and city location of people purchasing apps with the developers who created them, a practice not made clear
in Google's privacy policy. Google claims this is not a new practice, nor is it a bug within Google apps. The issue was brought to light by a developer himself, who pointed out that he could use the
contact information to "track down and harass users who left negative reviews or refunded the app purchase."
